I'd meant to work this into something larger on Obama's speech last night, but it's an interesting fact in its own right on how our politics have, in their natural course, mostly moved on from the Iraq War debate (for better and for worse): of the 77 Senators who voted to authorize the war back in October 2002, no more than 32 of them - 17 Republicans and 15 members of the Democratic caucus (i.e., including Lieberman) will still be in office come January (less if some fail to get re-elected, although Harry Reid's the only one of the 32 in much hot water; of course, Hillary and Biden have moved on to higher positions). 14 of the 23 who voted against the war could be back, although three of those are currently embattled (Feingold, Murray, and Boxer). Any number of major figures on our national scene now, including Barack Obama, Sarah Palin and Mitt Romney, had yet to win statewide office at the time.

That's reflective of a number of things, but most of all the changing of the guard as a lot of the Senate's longest-standing veterans have died or retired and the rate of turnover has been accelerating with big Democratic gains in 2006 & 2008 and likely big Republican gains this year. The GOP will be getting a very fresh start - by January, we'll have only 32 GOP Senators left who were elected before 2010 (and only 11 GOP Governors elected before 2010, including 2009-elected governors like Christie and McDonnell).
